Have to reboot WR11 to bring back eth0

Question

Hi all,

My device is connected to WR11. And it is constantly losing eth0 link. From log:
...
Nov 8 15:10:04 localhost kernel: [1830212.560725] sunxi_emac sunxi_emac.0: eth0: link down
Nov 8 15:10:08 localhost kernel: [1830216.563551] sunxi_emac sunxi_emac.0: eth0: link up, 100Mbps, half-duplex, lpa 0x40A1
Nov 8 15:10:14 localhost kernel: [1830222.560718] sunxi_emac sunxi_emac.0: eth0: link down
Nov 8 15:10:18 localhost kernel: [1830226.563599] sunxi_emac sunxi_emac.0: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
...

Sometimes i have to reboot WR11 to bring eth0 back. Has anyone else experienced this?

Thanks!

Answer 1

Hi

Have you tried to lock the speed and duplex on both sides?

do you still see the interfaces flapping?

you have to disable auto negosiation as well as set the sped and baud on the wr11

1. No i didn't - It is pilot project, and it is not good idea to play with it remotely. At least now i may reboot it.
2. Yes, just checked my nodes (i have 3) one of them is not responsive.
3. Probably, it is good idea. But in this case i have to have both devices on my table.

I notice more:
 in a couple hours (usually i try to connect back or so) link may be recovered itself;
it is may take 10-15 days without issues, later several times per day.

Thanks
